TRAVELING SUSPENSION-TRUCK.

SPECIFICATION forming part of Letters Patent No. 337,179, dated March 2,1886.

Application filed December 2, 1885. Serial No. 184,535.

T0 at whom it may concern:

Be it known that I, HENRY J. MoARDLE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Traveling Suspension- Trucks, of which the following isa specification.

Myinvention relates to that class of traveling suspension-trucks whichare used for the handling of beef and other carcasses in largerefrigerators and market-houses, my invention consisting of a detailfully described hereinafter, in the construction of the device wherebythe manufacture of the same is simplified, and an objection arising inthe use of the ordinary traveling suspension-truck removed.

In the accompanying drawings, Figure l is a perspective view of atraveling suspensiontruck constructed in accordance with my invention,Fig. 2, a transverse section of the same, partly in elevation; and Fig.3 a rear view with part of one of the points of the hook broken away.

A traveling suspension-truck, such as that forming the subject of myinvention, consists of the hook A, which may be either singlepointed ordouble pointed, as shown, and which is hung to a ring, B, swiveled tothe lower end of a bar, D, the upper end of which is bent so as to formtwo supports for the spindle a of a grooved wheel, F, which is intendedto run upon an elevated rail in the re frigerator or other room orapartment, such a rail being shown by dotted lines in Fig. 2. The bar Dhas below the wheel a beveled projection, b, which serves to guidethegrooved wheel onto the rail in applying the truck thereto in theusual manner. Ordinarily this projection consists of a separate blocksecured (No model.)

to the bar D by a rivet, two extra pieces being thus required, and someexpense being incurred in securing the block to the bar. I save the costof these extra pieces and the expense of the additional labor incidentto their use by simply striking up a tongue from the metal of the bar D,to form the guiding-projection I), this being readily effected by oneblow of a'power-hammer provided with suitable dies.

As traveling suspension-trucks, such as that forming the subject of myinvention, are made in very large quantities and at a low price, thesaving effected by my improvement in the formation of theguiding-projection b is an item of considerable importance; moreover,the projection is limited in width to about one-third the width of thebar D, so that it does not ofier that obstacle to the movement of thebar around sharp turns in the rail which is presented by the ordinaryseparate block, the latter having to be of a width as great as the barin order to permit the use of a rivet of proper size for securing it tosaid bar.

I claim as my invention- A traveling suspension-truck in which a wheeland hook are combined with a bar having the guiding-projection b,consisting of a tongue less in width than the bar and struck up from themetal composing said bar, all substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY J. MOARDLE.
